The Densité 3 UHD-3901-UC is a dual-channel HD/3G to 4K UHD upconverter, which is designed to upconvert and pro­cess HD signals for 4K UHD broadcast production.

The UHD-3901-UC features broadcast quality upconverts with high-quality scaler, motion adaptive de-interlacer and color space conversion from ITU-R BT.709 to ITU-R BT.2020. Frame buffer is provided to keep 4K UHD outputs aligned with respect to a reference signal. The 4K UHD signals generated are output on quad link 3G SDI as per SMPTE ST-425-5 and supports two sample interleave (2SI) and square division quad split (SDQS) outputs, which are user selectable. The HD/3G embedded audio and metadata are delayed accordingly to keep synchronization with video before re-embedding in the first 3G link.

There are many benefits to adding the UHD-3901-UC to workflows, enhancing production capabilities. The UHD-3901-UC interfaces with Grass Valley HD cameras and K2 Dyno replay servers (at 6X) to create 4K UHD signals that can then be delivered to a 4K UHD production switcher in a very economical way, instead of using the switcher’s mix effects banks. The optional HDR processor, UHD-3901-OPT-HDR, allows conversion from SDR to HDR formats, sup­porting HLG (ITU-R BT.2100) and PQ (SMPTE ST 2084, ITU-R BT.2100) formats, with conversion between formats.

The Densité UHD-3901-UC is a revolutionary product designed to complement existing applications, providing a simple way to move between HD/3G and 4K UHD formats as well as from SDR to HDR. The UHD-3901-UC cards accommodate a gradual adoption of HD production elements into 4K UHD broadcasting workflows, while protecting investment in installed equipment. These cards are useful in several applications.

When you need to produce content in 4K UHD, but have a mix of HD, 3G and 4K UHD cameras, the UHD-3901-UC provides the ability to create a common format for the final production. This is a great solution for live sports or other applications that often produce in HD along with 4K UHD and utilize a mix of cameras.

The card offers dual channels of upconversion and supports both two sample interleave (2SI) and square division quad split (SDQS) 4K UHD. The 4K UHD card easily enables conversion between the two formats for simplified interoperability.

When you want to use HD or 3G slo-mo in a 4K UHD production, the UHD-3901-UC processing module allows regular and slow motion HD or 3G cameras as well as other HD/3G sources to be used in 4K UHD productions by upconverting to a common 4K UHD format.

By utilizing the card in combination with HD/3G cameras enables use of 6X slow motion in a 4K UHD workflow. The UHD-3901-UC provides a method to take the slo-mo output from a 6X K2 Dyno Replay System server to create a 4K UHD slo-mo version.

When you need to integrate 3G SDI computer graphics with live 4K UHD production, the UHD-3901-UC can take the output of the graphics generator during production and produce the 4K UHD fill and key for the switcher. The UHD-3901-UC provides a readily available and simple solution for adding CG graphics to a 4K UHD production.

When producing 4K UHD productions that not only use HDR 4K UHD cameras, but also HDR 3G cameras and SDR HD cameras, the UHD-3901-UC can bring all sources to a common format, not just in resolution but also in color space. The UHD-3901-UC can convert from 3G or HD to 4K UHD, and it can convert from SDR to HDR, supporting HLG, PQ and S-Log.

When you want to add 4K UHD to your HD workflow that already uses IP cameras over 10G Ethernet, you can pair an IPG-3901 with TICO along with the UHD-3901-UC, and feed that into a 4K UHD switcher for instant 4K UHD production over IP.
